After upgrading to Windows 10 I lost my connectivity, Lan and wireless.
The error : one or more network protocols are missing from this computer
I found this command FIX the problem:
Open CMD (administrator rights)
Type : netsh winsock reset catalog
If still limited connection, try to uninstall Avast antivirus.
Should be work now, if not try with the suggestion in the link below:
